Altitudinal range: from the subalpine belt (potential vegetation: open, taiga-like forests dominated by Larix decidua and/or Pinus cembra and Rhododendron) to the alpine belt (potential vegetation: treeless Alpine grasslands and tundras, to the lower limit of perennial snow and the equilibrium line of glaciers)
Note: a species probably related to (or identical with) L. lapicida var. pantherina, with a thin, rimose to areolate, grey to smoke-grey thallus (reacting K+ yellow then red, medulla I+ violet, fide Hertel), black, non-pruinose, marginate, first immersed, later adpressed apothecia (c. 0.3-0.5 mm in diam.), a brownish hypothecium, a bluish-black epihymenium, 8-spored asci, and oblong to ellipsoid, simple, hyaline ascospores (12-15 × 5-7 μm); on siliceous (somehow calciferous?) rocks; only known from the type locality in the Western Alps (Switzerland).
